The idea of work and home lives being two separate things that require two distinct skill sets and personas is a product of the Industrial Revolution. Before that, the vast majority of people lived on the land and everyone had to contribute whatever they could to stay afloat while hoping their feudal lord did not show up and take all their property and praying for a good harvest. Life actually got a lot worse for a lot of people from about 1750 onward, as everyone rushed to the cities and ended up trapped in what today we would call a sweatshop environment, where very long hours in loud, hot, dangerous conditions were considered the norm and pay was typically absolutely terrible.
Fast forward a couple of centuries and a combination of rising wealth, civil and workers' rights movements and changes in technology have transformed the workplace repeatedly, with no two decades the same anymore. While this has some enormous downsides, like entire industries being automated out of existence and the death of job security and pensions, it also has some upsides. Worker deaths are at historic lows and discrimination and workplace abuse are finally being exposed and rooted out. Of course, how you experienced these changes is hugely influenced by when you were born, so tell us about your job and we'll guess just when that was!
